D.B. Cooper Update

You may have ended up here by googling D.B. Cooper. If not, google the name to learn more about this famous case. Now, we believe that this 36 year-old case is about to be broken by Sherlock Investigations.

D.B. Cooper is a name erroneously attached to a man who hijacked a Northwest 727 in 1971. He said that he had a bomb in a cheap plastic suitcase he carried. The man bought his plane ticket under the name Dan Cooper. The media later interviewed a D.B. Cooper. The name stuck forever to the case.

"Cooper" had the plane land, unload the 36 passengers, and picked up $200,000 in $20 bills, plus four parachutes. Soon after taking off again, he bailed out, never to be seen again. Even the yellow and red parachute was never found.

Many articles, some books, and even a movie, starring Treat Williams and Robert Duvall, have been inspired by the D.B. Cooper case.

Working on a lead we received, we've been on the case for several months. All the evidence we have fits the clues gleaned from the various articles and FBI press releases. We have photos, a fingerprint, and DNA evidence.

We believe that "D.B. Cooper" worked for Northwest Airlines (Northwest Orient at the time), was an experienced parachutist, lived in a Seattle suburb, grew up in the midwest, and was single. He even bought a house for cash two years after the famous hijacking.

About Me

Hi, I'm Skipp Porteous. I'm a New Yorker who lives in Manhattan. I specialize in wiretap and "bug" detection. The thing I like most about being a private investigator is being able to help people. I firmly believe that if you give, it will be given back to you.
I researched the unsolved crime of the century for 3 years and wrote the book "Into The Blast: The True Story of D.B. Cooper." It was published by Adventure Books of Seattle, and the editor of Adventure Book, Robert Blevins, co-authored it with me.
